Ursolic acid is a pentacyclic triterpene that belongs to the group of terpenoids and for its variety of pharmacological activities, related to their hepatoprotective effects, anti-oxidant, anti-inflammatory and anti-metastasis, is a subject of great scientific interest. This research aimed to obtain high purity ursolic acid in an easy, fast and economical way from the Clinopodium revolutum species known commercially as flor de arena. The process began with obtaining the extract of the dried leaves, from which ursolic acid was isolated using and the recrystallization technique was used for separation and purification. Finally we performed spectroscopic analyzes of IR and mono and twodimensional NMR to characterize the molecule. The total content and percentage of purity were determined by the UPLC technique. Among the most important results of the study, it was determined that this species is the one with the highest amount (4.864%) of ursolic acid among species of the Lamiaceae family. Among the conclusions, it is noted that this medicinal plant known as Clinopodium revolutum and marketed under the name of flor de arena or té indio endemic of Peru, grown mainly in the regions of Huánuco and Cajamarca, proved to be an important biofuente of ursolic acid, not only for its high content but also by the easy, economical and reproducible methods with which crystals of pure ursolic acid were obtained by the recrystallization technique.
